Struct Cartesian2d

pub struct Cartesian2d<X: Ranged, Y: Ranged> { /* private fields */ }

A 2D Cartesian coordinate system described by two 1D ranged coordinate specs.

Implementations

impl<X: Ranged, Y: Ranged> Cartesian2d<X, Y>

pub fn new<IntoX: Into<X>, IntoY: Into<Y>>( logic_x: IntoX, logic_y: IntoY, actual: (Range<i32>, Range<i32>), ) -> Self

Create a new 2D cartesian coordinate system

• logic_x and logic_y : The description for the 1D coordinate system
• actual: The pixel range on the screen for this coordinate system

pub fn draw_mesh<E, DrawMesh: FnMut(MeshLine<'_, X, Y>) -> Result<(), E>, XH: KeyPointHint, YH: KeyPointHint>( &self, h_limit: YH, v_limit: XH, draw_mesh: DrawMesh, ) -> Result<(), E>

Draw the mesh for the coordinate system

pub fn get_x_range(&self) -> Range<X::ValueType>

Get the range of X axis

pub fn get_y_range(&self) -> Range<Y::ValueType>

Get the range of Y axis

pub fn get_x_axis_pixel_range(&self) -> Range<i32>

Get the horizental backend coordinate range where X axis should be drawn

pub fn get_y_axis_pixel_range(&self) -> Range<i32>

Get the vertical backend coordinate range where Y axis should be drawn

pub fn x_spec(&self) -> &X

Get the 1D coordinate spec for X axis

pub fn y_spec(&self) -> &Y

Get the 1D coordinate spec for Y axis

Trait Implementations

impl<X: Clone + Ranged, Y: Clone + Ranged> Clone for Cartesian2d<X, Y>

fn clone(&self) -> Cartesian2d<X, Y>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<X: Ranged, Y: Ranged> CoordTranslate for Cartesian2d<X, Y>

type From = (<X as Ranged>::ValueType, <Y as Ranged>::ValueType)

Specifies the object to be translated from

fn translate(&self, from: &Self::From) -> BackendCoord

Translate the guest coordinate to the guest coordinate

fn depth(&self, _from: &Self::From) -> i32

Get the Z-value of current coordinate

impl<X: ReversibleRanged, Y: ReversibleRanged> ReverseCoordTranslate for Cartesian2d<X, Y>

fn reverse_translate(&self, input: BackendCoord) -> Option<Self::From>

Reverse translate the coordinate from the drawing coordinate to the logic coordinate. Note: the return value is an option, because it’s possible that the drawing coordinate isn’t able to be represented in te guest coordinate system

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
